Heh, I've gotta agree; Clow Reed and Yuuko. But there are definite differences, so it's still original art :O And now I'm interested in the story you're mentioning in your wall description.

Anyways, it's executed quite well; the smoke and the falling petals add a simply elegant background to a rich and gorgeous foreground of elaborately costumed characters. The text on this wall actually adds to it, and the stylized butterfly adds to the text, and therefore the entire overall wall.

Me like :3 +Fave
